HTTPJVMMaxHeapSize=4096M

I have an open ticket with IBM. They want me to add
HTTPJVMMaxHeapSize=4096M
to my notes.ini. I did. However upon restart it keeps changing it to
256M
Is there some server document, configuration document or something I need
to change?
I'm about to start auditing on notes.ini to find the culprit.

I got further...
If I use
HTTPJVMMaxHeapSize=1024M
it leaves it alone. Therefore I suspect Domino says 4096 is invalid and
drops it down to 256M.

STRJRN OBJ(('/gdi01/notes/data/notes.ini'))
JRN('/qsys.lib/rob.lib/ifsjrn.jrn') IMAGES(*BOTH)

Now if I could just figure out how to get this to display in character
format and allow me to search for 256...
SELECT * FROM TABLE (
QSYS2.DISPLAY_JOURNAL(
JOURNAL_LIBRARY=> 'ROB',
JOURNAL_NAME=>'IFSJRN',
STARTING_TIMESTAMP=>TIMESTAMP('2018-10-25-09.30.00'),
ENDING_TIMESTAMP=>TIMESTAMP('2018-10-25-09.50.00')
)) AS JT
WHERE JOURNAL_ENTRY_TYPE NOT IN('OF', 'CS');

They pump all updates to that file through the program LIBNOTES but there
are a few jobs which call that program to do the updates.
